A couple of things:
1- Add a Stamina bar for the girls, and make it so the last action counts, sometimes they just stop at the very edge of cumming.
2- The sex xp influence on the mc makes it so difficult to cum that it's almost impossible to get anyone pregnant after 50 xp. The girl will tire before you can reach halfway cum bar.
3- Increase the xp gain by the girls for every action during sex (so they get better faster and the mc cums faster even with high xp)
4- Spirit isn't going down after you use a spell.
This game is good and has potential, it's common to have problems or umbalanced features at the start. I'll keep following.
I'm really looking foward for blacks and asians
